Achieving MAC Fairness Using Binary Exponential Backoff (BEB) Algorithm in Wireless Adhoc Network

The Medium Access Control (MAC) protocol is the main constituent which determines the system throughput using IEEE 802.11 protocol in Wireless Networks. The MAC Layer system of the IEEE 802.11 protocol is also referenced as Distributed Coordination Function (DCF). In DCF mode, source nodes contend for the use of the channel in dispersed manner via the use of the Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) procedure. Using the CSMA/CA procedure, each source nodes sets up a back-off time according to a randomly selected interval from zero to the Contention Window (CW) size for an extra delay time before transmitting the data packets.
